Google's promo for its self-driving car prototype that made headlines last week was a hit. The spot, "A First Drive," features the tech giant's car, sans steering wheel or brake and accelerator pads, chauffeuring elderly and vision-impaired individuals around. Google is imagining the future of autonomous vehicles as a local, on-demand car service, and our reporter Gabe Nelson has the full story here. The spot comes in at No. 1 with 6,022,065 views.

Also new this week are dual World Cup spots from Hyundai and Kia. The Korean auto group is the official sponsor of the event, and is aiming to get as much bang for its buck possible. The first spot, "The Glorious Journey for All" from Hyundai, invites viewers and fans to submit their own World Cup-related photos and videos to a dedicated Web site that the automaker has created. It's ranked second by Visible Measures with 3,038,456 views. The Kia spot, "2014 FIFA World Cup Brazil," likens the creation of the World Cup stadium to the manufacturing of a car, complete with a Start/Stop button. It is ranked third by Visible Measures with 2,852,831 views.

Automotive News' Video Traction Chart, powered by Visible Measures, focuses on brand-driven social video ad campaigns. Each campaign is measured by True Reach, an MRC accredited metric that includes views from brand-driven and audience-driven social video clips. The data are compiled using the patented Visible Measures platform, a constantly growing repository of analytic data on hundreds of millions of videos tracked across hundreds of online video destinations.

Note: This analysis does not include Visible Measures' paid-placement (e.g., overlays; pre-, mid-, and post-roll) performance data or video views on private sites. This chart does not include movie trailers, video game campaigns, TV show, or media network promotions. View counts are incremental by week.
